Flash

"Make your own future. Make your own past. It's all... right... now."

- Barry Allen

Barry Allen is a student at Central City University who gained the access to the Speed Force that allowed him to move at tremendous superhuman speeds. Using these powers, he became a vigilante in Central City known as the Flash and was recruited by Bruce Wayne as part of a strikeforce meant to protect the Earth from the impending invasion of Steppenwolf after the death of Superman.

Following his recruitment to the team, Flash played a pivotal role in the resurrection of Superman. With the team now fully assembled, Flash greatly contributed to the successful assault against the forces of General Steppenwolf of Apokolips, forcing the alien invasion to retreat from Earth. Afterwards, Barry was hired for a position at the Central City Police Department's crime lab, much to his imprisoned father's delight.

Early Life
Barry Allen was born on September 30, 1992, in Central City, Ohio, to Henry and Nora Allen, the latter of whom was later murdered in their home while Henry was arrested for her death. Fueled by his determination to prove his father's innocence, Barry began studying forensic science in hopes of one day clearing his father's name.

Monitored by Lex Luthor
In 2016, Allen was among other superhuman individuals monitored by Lex Luthor for his research into the metahuman emergence. He was recorded on surveillance footage from a convenience store that showed him shopping for groceries before witnessing an assailant enter the store and hold the cashier at gunpoint. Acting quickly, Allen knocked the mugger aside and returned to his groceries, causing the electricity he generated to affect the lights overhead momentarily as he went to complete his purchase. The footage was included in Luthor's files that were stolen by Diana Prince before she turned them over to Bruce Wayne, who was able to bypass the encryption and review the information on the computer in his Batcave.

Apprehending Captain Boomerang
"One minute, I'm playing mahjong with me nana, then this red streak hits me outta nowhere!"

- Captain Boomerang

During a string of jewelry heists in Central City, Flash's attention was turned towards the criminal Captain Boomerang whom he arrested, but was fooled into letting him go when Boomerang convinced him that he had been impersonated. On their next encounter, Captain Boomerang managed to knock Flash out and tie him to his Rocket Boomerang, which was sent hurtling into the Earth's atmosphere. As the rocket finally began to descend back onto the ground, Flash managed to free himself and proceeded to capture Boomerang.

When Captain Boomerang attempted to rob the Central City Diamond Exchange, Flash arrived as Boomerang knocked out his partner with a boomerang to take the fall for the heist, chastising him for having no "honor among thieves" before arresting Boomerang and leaving him for the police to find.

Recruited by Bruce Wayne
"You can be whatever you want to be. You're brilliant, man. Absolute best of the best. I can't sit here and watch you run in place in Central City for some old dude who is not going anywhere."

- Henry Allen convincing his son to not visit him in prison anymore

Sometime in January 2017, Barry went to visit his father, Henry Allen, at Iron Heights Penitentiary, where Henry had been wrongly imprisoned after being convicted of murdering his wife Nora Allen in 2001. Barry and Henry talk about Barry's obsession with proving his father's innocence; Barry believes the original investigation was botched. Henry tells his son not to keep coming to visit him, which Barry responded to by asking him to never ask him to do again.

Meeting Bruce Wayne

Rescue at Stryker's Island
Arriving in Gotham, Barry and Bruce rendezvous with Diana Prince, who informs the latter on her progress with Victor Stone's recruitment. Just then, Barry sees the Bat Signal and excitingly reminds Bruce that it meant they should get going, leading to Bruce and Diana sharing a look over the young vigilante's behavior.

Meeting with Commissioner James Gordon, the three are joined by Victor Stone, whose father was one of the S.T.A.R. Labs scientists kidnapped by the Parademons. The group managed to figure out that the scientists were being rallied underground at Gotham Harbor, thanks to Victor. As the group arrived, they witness Steppenwolf mercilessly murder one of the scientists after she did not reveal the location of a Mother Box. As the League began their attack, Barry begins rescuing the rest of the hostages before joining in the fight against the Parademons.

When Barry returns to the fight, Diana has hold of her sword, so Flash uses his speed to move the hand back in her grasp. Distracted by his accomplishment, Barry loses his footing and tumbles to the ground below. As Steppenwolf approaches them, Barry is grazed in the leg by a Parademon blast and is nearly taken before being saved by Diana. However, Steppenwolf proves to be too strong for the ragtag team to handle, catching a missile fired from the Knightcrawler and using it to flood the area before escaping. Luckily, Aquaman saves them by slowing the tide with his trident, allowing Barry and the others to get to safety.

Resurrection of Superman
The League regrouped in the Batcave to plan their next move. After discovering the capabilities of the Mother Box in Cyborg's possession, the team decided to use the Genesis Chamber in the Kryptonian ship along with the Mother Box to resurrect Superman beliving that bringing him back not only completes the team but also increases their odds of defeating Steppenwolf,as a result result Victor and Barry dug up Clark's grave, with the pair noting the abnormality in their task and bonding over their powers.

After bringing Superman's body up, the team submerged the Kryptonian and Barry fired off an electrical charge that energized the Box, whose restorative energy field healed and revived the fallen hero. However, Superman, awakened disoriented and, believing them to be hostile, attacked the League, who were all but powerless against him. While Superman held back Diana, Arthur, and Victor simultaneously, Barry attempted to flank him, though this tactic quickly proved to be in vain as Superman could almost keep up with Barry's speed, much to his terrified amazement. Flash, in haste, attempted to evade Superman's attacks, but is knocked into the wall of the memorial and incapacitated.

Battle of Pozharnov
"Okay, just gotta go faster than the speed of light, far beyond the speed of light. You gotta break the rule, Barry, and you gotta do it now!"

- Flash

The team returned to the Batcave where Cyborg figured out Steppenwolf's plan. The team made a plan to take down Steppenwolf and stop the Unity, in which Barry plays a key part. Because of Silas' sacrifice, the League is able pinpoint Steppenwolf's location abandoned town located in Russia, Barry and the League took off in the Flying Fox to face the Apokoliptian. Upon arriving, Barry and the others observe as Batman leads the Parademons away and takes down the shield surrounding Steppenwolf's base. Barry then is tasked with running laps around the facility to build up a charge, which will be required to get Cyborg into the boxes. He is shot by a parademon, and has to take a few seconds to heal, but it's too late. The Unity forms, and the world is scorched, turning into a clone of Apokolips, with a Boom Tube opening to allow Darkseid to take full control of the boxes. Barry begins witnessing the destruction of Earth, and then remembers that he can reverse time to save the world. Realizing that all life on earth will be destroyed Barry breaks his one rule: going faster then the speed of light. As he runs times reverses to the point just before the unity activated and he manages to send Cyborg into the boxes, and after destabilizing the boxes, Cyborg and Superman separate them and prevent the Unity saving the Earth. A defeated but still determined Steppenwolf attempts to attack the league only to be stabbed by Aquaman, punched into the portal opened by Apokolips ruler Darkseid by Superman, and decapitated by Wonder Woman. Flash rejoins the time as they all get a glimps of the alien tyrant before the Boom Tube closes.

New Beginnings
"It's actually the worst job you can get in a crime lab." "Is this like a job-job?""

- Barry Allen and Henry Allen

After the battle with Steppenwolf, Barry returned to his normal life, thanks to recommendations from Bruce Wayne, Barry was hired for a position in the Central City Police Department's crime lab. Barry then visited his father, displaying his letter of employment while explaining that it wasn't the greatest position, but it was, in fact, a steady job for him.

Personality
Barry Allen is a remarkably intelligent and determined individual, becoming a highly skilled forensic scientist to prove the innocence of his imprisoned father Henry Allen in the death of his mother Nora Allen. As the Flash, Barry is determined to keep his secret identity a secret from others, demonstrated by the many excuses he came up with when confronted by Bruce Wayne, despite none of them being convincing enough to fool the latter. When finally exposed by Bruce, Barry was quick to agree to join the Justice League, due to his great desire to gain friends he could relate to.

However, despite his incredible powers and happy personality, Barry initially remained insecure and unsure of himself, since all of his League teammates seemed prepared to do battle against Steppenwolf's army. In addition to this, Flash had a penchant for drifting around and is plagued by multiple social disorders. However, following the battle against the Apokoliptian forces, Barry developed a stronger sense of confidence, as seen when he didn't hesitate to face the disoriented Superman after his resurrection, despite being visibly terrified.

Despite his tragic childhood, Barry is quite laid-back, witty, bubbly, somewhat childish and humorous, in stark contrast to the very calm, mature, dark and serious Batman, as well as most of the Justice League. Regardless of these differences though, Flash idolizes Batman, promptly expressing a desire to keep a Batarang, and gushing about seeing the Bat-Signal. Flash seems to idolize and admire Superman just as much, however, as the Man of Steel's heroic death is what inspired Barry to also more openly use his own metahuman powers and come out into the light as the Flash.

Barry's humorous attitude, however, initially annoys his fellow Justice Leaguers; Batman and Aquaman in particular, as well as Cyborg, and even the considerate Wonder Woman, though she still treats him with compassion.

Barry was nonetheless able to strike up friendships with most of them: bonding with Victor Stone over their similar accidents and insecurities, looking up to Bruce Wayne and Diana Prince as mentors, and developing a friendly rivalry with Superman, even challenging him to a race to the Pacific coast to see which one of them was truly faster. Barry can also be extremely serious on occasion, notably during his regular visits to his imprisoned father, Henry Allen.

Powers
"So you're fast." "That feels like an oversimplification."

- Bruce Wayne and Barry Allen

Speed Force Conduit: Barry Allen, after being struck by lightning and doused in nearby chemicals, gained a metahuman connection to the Speed Force, an extra-dimensional energy field, granting him many speed-based superhuman abilities.
 * Superhuman Speed: Barry is capable of moving at tremendous hypersonic speeds, an ability so powerful that his movements are invisible to the naked eye. Allen notably ran from a fridge to knock out a mugger and returned before the milk bottle he was holding could fall. Later, he was able to draw on a man's face when visiting his father in Iron Heights Penitentiary too fast for him or anybody else to notice. When the Justice League attempted to restrain a confused and angry Superman following his revival, Flash was able to evade the majority of the Kryptonian's attacks, only being hit due to stumbling. This shows that Flash is possibly slightly faster than super-powered Kryptonians. That is inconclusive however, since a few minutes after that, Superman was able to dodge Flash's super-speed charge (forcing Flash to run into Aquaman), though Barry may not have been using his full speed, and so later Superman and Flash decided to settle which one of them is faster with a race. At his fastest, and most crucial moment, Barry was able to force himself to move far beyond the speed of light in order to undo the Unity. In addition, the intensity of his speed allows the Flash to deliver superhumanly strong attacks (enough to leave Aquaman dazed for a few minutes after an accidental collision), as well as to run along vertical surfaces, across the surface of water, through solid matter, into other dimensions of the Multiverse, and even through time itself. Flash also can come to a full stop, despite the extreme inertia of his movements, allowing him to further the illusion of having not moved at all if he moves at super-speed and returns to his previous location, before anyone can notice it.
 * Regenerative Healing Factor: Flash's speed extends to him on a biological level, and thus, his metabolism functions faster than that of humans, which allows him to heal any injuries within a short time-frame. Hence, Flash required only a few minutes to heal from getting shot in the leg by a Parademon plasma bolt. His healing factor was almost instant.
 * Accelerated Metabolism: Because of Flash's accelerated metabolism, he burns calories at an accelerated rate, keeping his body slim and fit, so this requires him to intake a high amount of calories to function normally. Due to this, Flash describes himself as a "snack hole": a black hole of snacks.
 * Superhuman Reflexes: Flash possesses reflexes far greater than those of a normal human being. This allows him to easily react to danger and events, and perceive the world in slow motion. He was able to easily dodge a batarang thrown at him by Bruce Wayne, with it appearing to be moving at him in slow motion (at least 62 times slower than in real time), and Bruce himself almost frozen in place from Barry's perspective. While saving Iris West from a car crash, Barry sees her and the flying objects around her as if they were suspended in mid-air. Even the superhumanly fast Wonder Woman is far slower than Flash, and is seen to be moving in slow motion from his perspective. However, Superman is shown to be capable of moving at a similar speed, able to nearly match Flash on one occasion, and outpace him on another, to the point where a friendly wager was made between the two afterwards in a race to see who was truly faster.
 * Extreme Force Generation: While moving at an accelerated speed, Flash generates superhuman levels of momentum, which allow him to enhance the force behind his attacks, impacts, and collisions, often propelling people and objects several feet, that he uses to compensate for his average strength. Hence, Flash was able to easily mow down an entire squad of Parademons by colliding with them at immense speed, defeat Captain Boomerang in the same swift manner, sending a mugger flying with a single push. When saving Iris from her car accident, Flash had to carefully guide her out of danger to prevent her from getting whiplash. When Flash accidentally collides with the extremely durable Aquaman, he sends the latter flying into some steps, breaking them and leaving the Atlantean dazed for several minutes.
 * Superhuman Agility: Flash's agility, balance, and bodily coordination are enhanced to superhuman levels, allowing him to navigate while moving at superhuman speed. Thus, Flash managed to dodge most of the attacks from Steppenwolf and some from Superman. This coordination, however, isn't an intuitive trait, as Barry is still slightly clumsy, sometimes tripping over himself mid run.
 * Superhuman Stamina: Flash's body can handle the stress of moving at superhuman speeds for extended periods without getting tired or weak, so long as he's not running on an empty stomach.
 * Superhuman Durability: Barry is capable of resisting tremendous kinetic impact forces that could easily crush or kill a human, without suffering any serious external or internal injuries.
 * Intangibility: Flash can phase himself through solid objects by vibrating his molecules at super speed. He quickly phased to avoid Darkseid's destruction in order to go back in time.
 * Transdimensional Travel: Barry is capable of breaking the dimensional barrier with his speed to traverse between dimensions within the Multiverse.
 * Time Travel: Flash can run fast enough to break through the fabric of the space-time continuum, enabling him to travel forward or back in time to monitor or alter past events. Flash notably went back in time a few minutes, to help Superman and Cyborg stop the Unity in time, and later, with the help of Cyborg's calculations, the Flash from an alternate future traveled back to warn Batman of the potential danger Darkseid poses, showing Bruce a vision of the Knightmare future.

Abilities
"You can be whatever you want to be. You're a brilliant man. Absolute best of the best."

- Henry Allen to Barry Allen


 * Genius-level Intellect: Barry Allen is an exceptionally intelligent science enthusiast, with aptitudes in physics, forensics, and engineering. Notably, Barry was capable of designing and building his Flash suit from anti-friction material employed by NASA, impressing even Batman with the sophistication. Since his childhood, Barry has been devoted to dedicating himself to studying forensic science to prove his father's innocence in the murder of his mother.
 * Expert Engineer: Barry Allen possesses an intimate understanding of quantum mechanics, mechanical engineering, and electronics, allowing him to construct the sophisticated Flash suit using materials that, in addition to holding up against immense levels of heat and friction, ground the excess currents of energy he experiences while moving at tremendous speeds.
 * Musician: Barry is capable of playing the viola.
 * Bilingualism: Barry speaks his native English and gorilla sign language.
 * Combatant: To be added

Equipment

 * Flash Suit: Barry Allen wears a protective scarlet suit with high tensile wires holding the various pieces together, emblazoned with a golden lightning bolt design on the chest, like his superhero alter-ego the Flash. The suit is composed of specific materials, with Bruce Wayne noting that it is constructed from the same silica-based quartz fabric employed by NASA to protect spaceships during re-entry from burning up. The suit is worn by Barry to protect him from the immense friction encountered when he runs, as well as being overall resistant to extreme temperatures. In an alternate future where Superman becomes a tyrant of Earth under the control of the Anti-Life Equation, Barry wears an armored version of the suit designed by Bruce Wayne. This suit is more heavily armored and streamlined, while also having a retractable face shield that allows Barry to smash through obstacles without sustaining damage.
 * Cosmic Treadmill: In an alternate future the Cosmic treadmill is a powerful treadmill built by Cyborg using a Mother Box. It was used by the Flash to travel back in time and stop Darkseid and Superman's conquest of Earth.
